The nuns studying at the Pontifical Urbaniana University live at a campus in Castel Gandolfo, a 90-minute commute away.

“They lose so much time traveling,” said Sister Genowefa Kudlik, the Polish nun who runs the Castel Gandolfo campus.

It was held in a converted monastery in the hills overlooking Lake Albano, within view of the papal summer residence at Castel Gandolfo across the lake.

The Vatican observatory’s current astronomers mostly split their time between Castel Gandolfo and Mount Graham, Ariz., where the Vatican operates a telescope in partnership with the University of Arizona.

All three work or worked in the Specola Vaticana, or Vatican Observatory, just off the papal gardens at Castel Gandolfo, a short drive from Rome.
